In hopes of getting the buildfarm back to green, I went ahead and pushed
a slightly more aggressive form of this --- I took out the worker-specific
detach function altogether.  We can resurrect it if we ever have a more
plausible idea of how to do worker recycling, but for now I don't see a
reason to waste bytes on useless and incorrect code.
